Just dropped $16 on the pt mini 2 at my local-ish b&m, so $11 on the full tank is a good price if its legit. My only issue with these tanks so far is the stainless drip tips - After 5-6 pulls I get that metallic taste and have to switch it up. PT 2 with a ceramic drip tip is the way to go for me, but happy you're enjoying it. Pretty low maintenance, unless you get into rebuilding your own coils. Even then, not too much fuss. Or you could order a bunch of cheap replacement heads from fast tech and, with a little routine cleaning, be good to go for quite some time.
